About this file

Attachment 8 contains before and after photographs of the Madonna Creek Dam, documenting a significant geological slide that occurred between 2020 and 2023. The images were taken at Miramontes Ridge Open Space Preserve and show the progressive damage to the dam's slope and surrounding terrain. The first set of photos from 2020 depicts the dam with a stabilized embankment featuring rock revetment and a sandy slope with some vegetation. The 2023 photos reveal a substantial erosion event, with large sections of the slope collapsed, exposing dark soil and creating a significant gouge in the landscape. The slide appears to have dramatically altered the dam's structural integrity, with exposed earth, fallen vegetation, and visible structural damage across multiple perspectives of the site.

The photographic documentation appears to be supporting materials for the upcoming biological services Request for Professional Qualifications (RFPQ) for the Madonna Creek Dam Repair Project. The images provide visual evidence of the site's current condition, which will likely be critical for potential bidders to understand the scope and complexity of the required repair and restoration work. These photographs will help prospective biological service providers assess the environmental impact, potential ecological disruption, and restoration challenges associated with the dam's recent geological event.
